Alcatraz marks 50th anniversary

The National Park Service celebrated the 50th anniversary of Alcatraz Island's closure as a federal penitentiary on March 21 with an exhibit of newly discovered photos of the prison's final hours. The new display opened five decades after the last shacked prisoners were taken off the infamous prison in San Francisco Bay that once held the likes of gangsters Al Capone and Mickey Cohen.
